Purpose: To test different substances drano
will dissolve.Hypothesis: It is most likely that drano
is in actuality a very strong base. Because of this it is the hypothesis
of this experiment that drano would dissolve organic materials like
hair and papers, but not inorganic materials like metals.

Equipment: Required for this experiment is
drano, test tubes, water, and various substances to test upon.

Procedure: Take each substance one at a time
and apply drano to it, observe and record results. Dilute with water before
disposal.

Observations:

Object

Effect drano has upon it

Human hair

Noticeably dissolved some of the hair, however, hair remained clogged
in the test tube.

Bullet Casing

Nothing real noticeable changed with the bullet casing initially, however,
after about 10 minutes, the casing looked slightly shiner.

Paper Napkin

no noticeable effects

Black snake fireworks

After roughly 30 minutes, color change from charcoal black to white
and noxious gasses were noticeable.

Used tea grains

no noticeable effects

Daddy longlegs spider

Initially there was no noticeable effect, spider died after about 1
minute. Within 2 hours, the spiders legs were dissolved.

Conclusion: It was apparent that the drano
didn't really 'eat' through anything, rather, it was with prolonged contact
with the drano that actually causes substances to dissolve. It is
also observed that it is not readily predictable whether or not the drano
works better on organic materials or inorganic materials.
